THK DCMA Series Change Nut

The THK DCMA Series is a change nut that easily converts linear motion into rotary motion, and can do the reverse just as smoothly, all with 70% efficiency. Because it has a large lead, it’s well suited for building a fast feed mechanism that runs on low speed rotation.

This series is designed with wear resistance in mind, helping it hold up well over long term use in demanding transmission setups. It’s a practical choice for applications where you need reliable motion conversion without sacrificing speed or durability.

The dynamic permissible thrust (F) for this series ranges from 2300 N to 28500 N, giving it enough capacity to suit a variety of load conditions.
